Speaking Out About (Over-)Population
There is a sizable number of people concerned about overpopulation. They are being drawn together by a new initiative, the Global Population Speak Out, aiming at undermining “a taboo of sorts against public discussion of overpopulation”:
GPSO was born of a simple idea: What if a large number of qualified voices worldwide, many of whom might not have emphasized the topic previously, were to speak out on overpopulation all at once? The strength of numbers might help weaken the taboo and bring population issues to a more prominent position in the global discussion.
You can see the efforts of the participants in this page. The main topics are the concern of overpopulation as a major driver in resource depletion (i.e. there are too many people consuming too much too quickly) and especially in ruining the environment.
Readers of this blog will not be surprised to hear that I do not believe in gloomy forecasts, and particularly so in the gloomiest of them. I am also not convinced that there is a present situation of overpopulation right now: some back-of-the-envelope calculation seems to suggest full capacity would be around 15 billion people, even allowing for everybody to become a well-fed American. And who can forget that the current size of human population is the consequence of a struggle that must have lasted for a good part of the last million years?
Still, I also believe GPSO has a good point to make.
Let’s start considering their sensible attitude to past abuses of the overpopulation issue. Simply too many people have married the cause in the past because afraid of having to deal with millions of poor, black or Asian people. And still to this day, it is not difficult to find pea-brained arguments pitting children against the environment.
I do not see any trace of that in the original GPSO letter.
What I can see among the unfortunate repetitive claims about upcoming disasters, is a concern for what perhaps should not be, but still can develop in a big issue. My model for human activity in general is that of the long-distance travelers putting their stuff into the car’s trunk. No matter how much they plan to take with them, still they will more likely than not occupy the full trunk.
In other words, it is not much a matter of the size of the car, or the volume of things they want to bring to their destination: as far as humans are concerned, the whole available space is always to be wholly used. For another example, just check how many 1-h business meetings amazingly last for a full hour; and how easy it is for thousands and thousands of newspaper editors to fill up exactly all their available print areas, day after day, down to the eighth of an inch.
This ability for making full use of all resources within reach is something we should be very proud of; and wary, as there is little indication for when limits are actually reached. It always looks like there is more space in the trunk, and by speaking just a little faster more topics can be crammed in a meeting. But there is a limit, and the wise traveler will make sure loading is stopped early enough as to avoid damaging the car (or the stuff already loaded).
That’s why population should not be a taboo subject. And besides, it is also a topic closely related to personal freedom. For reasons too long to deal with now, women the world over have always seen their worth measured in the number of children they could bear. In theory, there is no actual need for that to continue any longer, and yet it still happens in one form or another pretty much everywhere.
Population sizes, from this point of view, can be seen as a symptom of an underlying bigger social problem. And who would want to make a symptom a taboo subject?
